Pruning Your App- Good Practices for Reducing App Size
summary
Practical recipe: convert PNGs to WebP and vectors to drop image weight (one photo 1.6 MB → 830 KB with lossless WebP, then to 48 KB at 80% lossy), enable R8 minification and resource shrinking to remove dead code (Google I/O app shrinks 18 MB → 6 MB), use Play Feature Delivery for conditional and on‑demand modules (ARCore added ~5 MB only for supported devices), and enforce CI size gates with APK Analyzer, Spotify Ruler or emerge.tools to catch regressions.
